Zex wet kit

I am thinking about putting a zex nitrous kit on my 08 4.8 what would be the perfect shot to add with out me messing up my motor. I am thinking about the gone in sixty minutes kit and getting the 75 shot upgrade.

you should be good 75 is safe.
The only bad side about this is that our trannies are weak really weak. Ive read up on another forum where they asked the same question, and he said up to 150 was ok, just dont be foolish with the nos.

i dont know if its allowed to post links but heres the thread, read up on it.

I would worry about the driveshaft also, I just watched a youtube video last night of a NNBS with a supercharger and a shot of nitrous. I will try and find it for you, but you've got to remember that you have aluminum heads on that motor maybe not the best thing to try without some beefing up. Anyways the guy ran fine on the dyno with the engine only, but as soon as he hit that shot of nitrous it tore the stock drive shaft in half! I would do a supercharger instead, and then you'll get a steady 100hp increase. And who knows with that tune you have, they can tweak it for some more hp. :glasses:

i have a 01. 5.3 has some bolt ons but i run 125shot on my truck also. motor runs good. last yr i blowed the tranny and the yr before got the rear end. it happens and can happen with the supercharger to. ive run nitrous on almost all my rides. this has been the first to break. but the trucks are not made to do what we do to them and stock sucks and will break. i had the beast bild in the tranny and a trutrac system with 3.73 gears in the rearend. so far no problems

I dont plan on going over a 75 shot. And i do plan on a turbo and a cam swap and a gear swap and some headers to. I could go all night on what this little 4.8 is gonna have done to it by feb of next year.
